Audiologist has said that I have 8mm domes. I think I actually have 7mm domes. Two reasons:
The two pencil lines are 8mm in width; it’s not really close. There’s a lot of empty space.
I can’t actually find 8mm domes with that design. I can find Starkey 7mm Comfort Domes with that design. But the Starkey 8mm open-fit domes have a different design.
